Difference between maximum and operating pressure
•
The maximum pressure is the highest possible pressure a compressor can generate.
•
Once the maximum pressure has been reached, the compressor switches off (auto-stop). As
soon as the pressure starts to decrease, it switches on again (auto-start).
•
Maximum pressure is the pressure measured inside the compressor.
•
There is a lower pressure on the outlet of the compressor. The pressure you actually work
with remains. The operating pressure may vary according to the connected airbrush gun.
Troubleshooting
Problem
Cause
Solution
The motor does not run.
1. Electric cables are defective.
1. Check the electric cables and
replace them if necessary.
2. The internal cable connections
are defective.

fective.
1. Replace the bearings.
2. Connecting rod screws are
loose.
2. Re-tight or replace the screws.
The airbrush gun does not
work properly; there is not
enough vacuum pressure.
1. The vacuum air connection is
not tight.
1. Seal the air hose with sealing
tape.
2. The air hose is torn.
2. Replace the air hose.
3. Cylinder cover screws are
loose.
3. Re-tighten the screws.
The motor, running regu-
larly, does not produce
enough or any air pres-
sure.
1. Valve and diaphragm screws
are loose or set to the wrong posi-
tion.
1. Open the front cover, re-tighten
the screws and set the diaphragm
screws to the correct position.
2. The valve has been destroyed
because too much pressure has
been applied during work.
2. Replace de intake plate or the
valves.
